<h3 id="rationale">Rationale:</h3>
<p>You appear to be missing the space on the left side of the operator.
Shell in general, and <code>[</code> in particular, is space sensitive.
Operators and operands must be separate tokens.</p>
<p>Please ensure that the operator, like the <code>=</code> in the
example, has a space both before and after it.</p>
<h3 id="exceptions">Exceptions:</h3>
<p>None. If you're comparing values in C style reverse order like
<code>[ -eq == $1 ]</code>, use quotes: <code>[ "-eq" == "$1" ]</code>.
Also, it's pointless since <code>[ a = b ]</code> doesn't assign.</p>
